In March 1800 using three thermometers, a prism and a piece of white card William Herschel made one of science’s most ground breaking discoveries, infrared radiation. Used today in devices ranging from TV remote controls to space satellites, infrared is helping us to push boundaries in medicine, understand global warming, and photograph the furthest reaches of our universe. This year we explore how Herschel made all this possible through his discovery of invisible light.
